Abstract

The invention discloses an ecological breeding mode for weever and corbicula fluminea. The ecological culture mode is characterized by comprising the following steps: S1, digging a pond as an ecological culture area for weever and corbicula fluminea; S2, injecting purified water into the pond; S3, cultivating and planting chlorella and diatom at the bottom of the pond; S4, putting weever fries andcorbicula fluminea fries into the pond; S5, putting bait into the pond; S6, observing the growth condition of the weever at regular time; S7, managing the water quality; and S8, conducting quarantineinspection on the weever while observing the weever. The design is reasonable, water in the pond is purified regularly, the hydrilla verticillata in the pond can decompose excreta of perches and corbicula fluminea, it is guaranteed that water is clean, meanwhile, a water source is not polluted, the corbicula fluminea reduces organic and inorganic nutrient substances in water by ingesting microalgae and organic particles in the water, growth of shells plays a role in carbon sequestration, and therefore culture wastewater discharge is reduced, and carbon dioxide in the atmosphere is reduced.

Description

technical field [0001] The invention relates to the technical field of ecological breeding, in particular to an ecological breeding mode of perch and river clam. Background technique [0002] Fishery development is the best way to solve the problem of high-quality protein supply in the world. In recent years, the aquaculture industry has developed rapidly, and the farming model has also changed from single-species farming to high-density large-scale development. However, when aquaculture is carried out in inland lakes and reservoirs, a large amount of fertilization, baiting, and medication have caused problems such as fragmentation of the ecosystem of lakes and reservoirs, overstocking, single fishery structure, deterioration of water quality, serious decline in fishery resources, and deterioration of water quality. Therefore, research on aquaculture in inland lakes and reservoirs has gradually developed from past experience-based stocking to quantitative dynamic model manag...
